Base Directories

DuckTest uses a root directory when looking for all files. By default, DuckTest::Config
will use Rails.root as it's own root directory. In an attempt to help keep config files from being complicated and messy, DuckTest employs a base directory for runnable and non-runnable files.

runnable_basedir is a base
directory that should be located directly off of the {DuckTest::ConfigHelper#root root} directory and is automagically factored in when searching for files that are runnable.

watch_basedir is a base
that should be located directly off of the {DuckTest::ConfigHelper#root root} directory and is automagically factored in when searching for files that are non-runnable.

The main reason for the existence of the base directories is to help ease the pain of configuration by eliminating the need to include directory names in filter and mapping expressions.

runnablebasedir and watchbasedir attributes trickle down into all of runnable, watch, map blocks, however, you do have the option of overriding for a specific block by passing a value
to the block. For example, let's say that you want to watch some of the files in the app lib directory. You could do that in a couple of ways.
